I'm conflicted is comparing a whole country travel distance to a state the same or I'm missing something? Genuinely curious. If we are talking about size of just a state do we Europeans have anything close to it?
I feel that the 800 players count is severely misleading counting, they've announced no Linux support and vanguard changes for months now most people already stopped playing LoL on linux, this 800 number is counting now not a accumulative number.
Mine would have to be Hollow man (2000) it was on TV at the time and for some reason as a kid watching the shifting both the animal and the human scene where they turn invisible where the skin disappeared then his muscles and veins, was absolutely terrifying, I don't remember well but my parents said I wouldn't let them sleep for weeks.
I don't think I can ever get enjoyment out of a battlefield game again after 3, I don't know if the times were different or the game itself was just that fun to play, I did get the new one in hopes of having that feeling again but it doesn't feel like battlefield anymore.
Easiest way would be to go to your codex, select a category, melee for example and make and level up every single weapon there, sentinels, warframes you get the idea, anything you can level up gives mastery, even completing the star chart by unlocking every mission, somethings will be harder or expensive to get or behind multiple days of farm aka most of stuff in open world but that's how everyone does it.
Which is actually pretty good imo
